You need $40 to buy a new pair of shoes. if you have saved $15. which inequality models how much more you must save?
a: s + 15 + ≥ 40
b: s + 15 + ≤ 40
c: s - 15 ≥ 40
d 40 + 15 < s

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2
